Metal rotor flowmeter has the advantages of simple structure, reliable operation, wide application range, accurate measurement and easy installation. With high temperature resistance, high pressure resistance of metal rotor flowmeter has a common type and anti-corrosion type. The above two types are divided into field indicating metal rotor flowmeter (LZZ-) and electric remote transmission metal rotor flowmeter (LZD-), ordinary flow sensor, instrument material for (1Cr18Ni9Ti), anti-corrosion type for (1Cr18Ni9Ti) lining PTEF.

If the metal rotor meter measures a medium containing ferromagnetic particles, a magnetic filter should be installed at the entrance of the meter. Its material should be the same as the corresponding flowmeter.
